Generate high-quality presentations programmatically using SlideSpeak's slide-by-slide API.

API Documentation: https://docs.slidespeak.co/basics/api-references/slide-by-slide/

API Specification Summary

Endpoint

POST https://api.slidespeak.co/api/v1/presentation/generate/slide-by-slide

Required Fields

Top-level:

template: string - Template name (e.g., "DEFAULT")
slides: array - List of slide configurations

Per slide:

title: string - Slide title
layout OR layout_name: string - Layout type (mutually exclusive)
item_amount: integer - Number of items (must match layout constraints)
content: string - Slide content

Optional Fields

Top-level:

language: string (default: "ORIGINAL")
fetch_images: boolean (default: true)
verbosity: "concise" | "standard" | "text-heavy" (default: "standard")
include_cover: boolean (default: true)
include_table_of_contents: boolean (default: true)
add_speaker_notes: boolean (default: false)

Per slide:

images: array of {type: "url"|"stock"|"ai", data: string}
chart: object - Chart configuration (for CHART layout)
table: string[][] - Table data (for TABLE layout)

Layout Constraints (Official API Requirements)

From API documentation:

The item_amount parameter must respect the item range constraints for each layout type.

Fixed item_amount requirements:

comparison: exactly 2 items
swot: exactly 4 items
pestel: exactly 6 items
thanks: 0 items

Other layouts: Use appropriate item_amount based on your content needs.

Official Example

See the official API documentation for complete examples including:

ITEMS layout (wildlife presentation)
TIMELINE layout (conservation timeline)
COMPARISON layout (threats vs solutions)
BIG_NUMBER layout (key statistics)
TABLE layout (regional KPIs)

Usage Approach

Generate intelligent, high-quality presentations:

Understand user requirements - What topic, how many slides, what style
Expand and enrich content - Transform user's brief input into detailed, professional content
Gather supporting information - Use web_search when needed for facts, data, examples
Select appropriate layouts - Match content type to layout (data→BIG_NUMBER, comparison→COMPARISON, etc.)
Generate configuration - Create well-structured JSON following API spec
Call the tool - slidespeak_render(config=your_config) with fetch_images: false (default)

Layout selection heuristics (keep it flexible, but consistent):

ITEMS: Use when you have parallel points of the same “level” (features, benefits, principles, checklist). It’s the safest default.
COMPARISON: Use when the slide naturally splits into two sides (Before vs After / Problem vs Solution / Us vs Alternatives / Option A vs B). Ensure both sides have a clear label and comparable density.
BIG_NUMBER: Use when you can express outcomes as KPIs, milestones, targets, or headline metrics (even ranges/goals are better than vague adjectives).
TIMELINE: Use for phased execution, roadmap, rollout, milestones. Each phase should have an action + an output (what is done + what you get).
SWOT: Use for structured risk/strategy review (market entry, product strategy, competitive context). Keep all quadrants at similar granularity.
TABLE: Use when the content is inherently row/column aligned (region × KPI, plan × cost, tier × feature). Avoid forcing table-ish data into ITEMS.
CHART (optional): Use for trend/share/distribution when you can provide dimensions and rough values/relationships.

Fallback rule:

If the content doesn’t really fit a specialized layout, degrade to ITEMS rather than forcing it.

Key principles:

Let your reasoning guide layout selection
Create rich, professional content with depth and substance
Respect the 4 fixed item_amount constraints (comparison=2, swot=4, pestel=6, thanks=0)
Default to fetch_images: false - Focus on strong content instead of relying on images
Use charts and tables for data visualization when appropriate
Expand user's brief inputs into comprehensive, well-structured content

Content Expansion Strategy

Transform brief user input into comprehensive, professional content:

1. Content Enrichment Principles

Expand each concept: User says "AI应用" → Expand to "AI应用：智能推荐系统提升用户转化率30%，自然语言处理实现客服自动化，计算机视觉赋能质量检测"
Add concrete examples: Instead of "提高效率" → "提高效率：自动化流程减少人工操作80%，实时数据分析支持快速决策，智能调度优化资源利用率"
Include data/metrics: Add numbers, percentages, timeframes to make content credible
Provide context: Explain WHY something matters before listing WHAT it is
Use the Rule of 3: Present 3-4 supporting points for each main idea

2. Professional PPT Design Guidelines

Content Structure (优秀PPT的黄金法则):

Progressive disclosure: Start with big picture, then dive into details across slides
Problem → Solution flow: Establish pain points before presenting solutions
Evidence-based: Back claims with data, case studies, or specific examples
Action-oriented: Each slide should drive toward a decision or next step

Writing Style:

Concise but complete: 1-2 sentences per bullet, each sentence adds value
Active voice: "AI提升效率40%" not "效率被AI提升了"
Specific over vague: "降低成本200万元/年" not "大幅降低成本"
Parallel structure: Keep similar items in similar grammatical form

Visual Hierarchy:

One core message per slide: Title should reveal the conclusion
3-5 bullets maximum: More than 5 items? Split into multiple slides or use table
Layered information: Main point (bold/emphasized) → Supporting detail → Example

3. Content Formatting Heuristics

Aim for "PPT-friendly inputs", not essays:

Prefer labelled chunks over prose: Label: point, point, point. is easier to format into bullets
Keep a slide single-topic: one slide = one message, supporting points only
Maintain consistent granularity within a slide: don't mix strategy-level bullets with low-level implementation details in the same list
Add at least one "anchor" when natural: a number/time/comparison/constraint/actionable mechanism (helps the slide look credible)
Avoid empty hype words: "revolutionary / disruptive / ultimate" tends to lower perceived professionalism
No images by default: Let content stand on its own merit. Only suggest images if they're truly essential to understanding

4. Content Generation Examples

❌ Weak (too brief):

Title: "产品特点"
Content: "功能强大. 易于使用. 性价比高."

✅ Strong (expanded & detailed):

Title: "核心竞争优势"
Content: "技术领先：采用最新GPT-4架构，响应速度提升3倍，准确率达98%. 用户友好：零代码配置界面，10分钟即可上手，支持20+语言. 成本优势：按量计费模式，中小企业月均节省5000元，提供免费试用期."

❌ Weak (generic):

Title: "市场机会"
Content: "市场规模大. 增长快. 竞争少."

✅ Strong (specific & data-driven):

Title: "千亿市场蓝海"
Content: "市场规模：国内企业级AI市场2024年达1200亿元，年复合增长率35%. 需求缺口：85%的中小企业仍依赖传统软件，急需智能化升级. 竞争态势：头部玩家聚焦大客户，中小企业市场渗透率不足15%，存在显著机会窗口."

Success Criteria

Configuration follows official API specification
Fixed item_amount constraints are respected
Content is detailed, specific, and actionable - not generic or superficial
User's brief input is expanded 3-5x with concrete examples, data, and context
Layout selection matches content type
Presentation tells a compelling story with clear narrative arc
No reliance on images - content quality stands alone

Quality Self-Check

Content depth checklist:

Each bullet has specific details (numbers, examples, mechanisms)
Main claims are backed by evidence (metrics, case studies, comparisons)
Content answers "So what?" - explains impact and relevance
Terminology is precise - no vague words like "很好"、"强大"、"先进"
Each slide has 1-2 sentences per point, not just keywords

Structural quality:

Each slide's content can be visually separated according to its layout
Bullet candidates read like talking points, not paragraphs
Narrative arc: context/problem → approach → mechanism → value → evidence → next steps
Progressive detail: Start broad (overview), end specific (action plan)

Professional polish:

Titles are outcome-focused: "提升转化率40%" not "优化方案"
Parallel structure maintained within each slide
Consistent granularity (don't mix high-level strategy with low-level tactics)
Active voice and confident tone throughout

Content Expansion Workflow

When user provides brief input like "生成一个关于AI产品的PPT":

Analyze intent: What's the goal? Sales pitch? Product demo? Technical overview?
Define structure: Typically 8-12 slides covering:
- Problem/Opportunity (with market data)
- Solution Overview (with key differentiators)
- Core Capabilities (with technical details)
- Use Cases (with specific examples)
- Results/Impact (with metrics)
- Comparison (with competitive analysis)
- Roadmap (with timeline)
- Next Steps (with clear CTA)
Expand each section:
- Take user's keywords and turn them into full sentences
- Add context (why it matters)
- Include specifics (how it works)
- Provide evidence (data, examples)
- Show impact (outcomes, benefits)
Validate completeness: Could a stranger understand this without you presenting?

Remember: Your job is to transform sparse user input into presentation-ready, detailed content that tells a complete, compelling story.
